Video: Dragon arrives at space station

Climbing into a clear night sky, a Falcon 9 rocket soared into space early Thursday with the EchoStar 23 commercial communications satellite from launch pad 39A at NASA’s Kennedy Space Center in Florida.

Four veteran astronauts have been selected to train for launch aboard new commercial crew capsules being built by Boeing and SpaceX that are intended to ferry astronauts to and from the International Space Station starting in 2017, NASA announced Thursday.

A total of 11 spacecraft will be deployed beginning about 1.5 hours after liftoff. SpaceX is aiming to launch the mission from pad 4 East at Vandenberg Space Force Base on July 23 at 11:13 a.m. PDT (2:13 p.m. EDT, 1813 UTC).
